In June 2003, he became the Lord Chancellor and the first Secretary of State for Constitutional Affairs. He was called to the Bar (Inner Temple) in 1974 and was appointed Solicitor General in May 1997. Between 1974 and 1997 he was a commercial barrister, and was involved in many significant commercial, industrial and financial issues of the day.
In 1997 he joined the Blair government as Solicitor-General, moving a year later to the Cabinet Office, becoming involved in all the critical issues which faced the government from 1998 until the 2001 election.
In 2001, after the general election, he became Housing, Planning and Regeneration Minister and in 2002 he became Criminal Justice Minister. In both these jobs he was engaged in leading genuine public service reform, for example in relation to the planning system and the criminal justice system.
In 2003 he became Lord Chancellor, with the remit of abolishing the office. He concluded, pretty quickly, that the aims of abolition could and should be achieved through reform not abolition. In conjunction with the then Lord Chief Justice he worked out a detailed new relationship between the judiciary and the executive, which was embodied in the Constitutional Reform Act 2005.
His reform included the creation, for the first time, of a Supreme Court for the UK, the creation of a commission to appoint judges, making a full-time independent judge the Head of the Judiciary for England and Wales, and introducing an elected Speaker for the House of Lords.
In 2007 he became the first Secretary of State for Justice bringing together courts, prisons and justice policy for the first time. He was responsible for leading a department with a budget over £10 billion and over 80,000 employees. He had the confidence of the justice system in leading his department.
He dealt on a wide range of issues for the UK, at the highest level, meeting frequently with foreign leaders for the government, including the presidents or Prime Ministers of China, France, Australia, Thailand, Turkey, New Zealand, India and Pakistan.
He dealt extensively with the EU, both with member states and the European Commission, and also with the USA, meeting and negotiating with members of the US administration (Democratic, and Republican alike) and meeting, dealing with and speaking widely to commercial, academic, legal and more general audiences in the States. He has established good links with China, in particular encouraging, over a long period, close commercial law links.
He has wide commercial and political experience involving successful leadership at the highest level. He has wide knowledge of and is known to governments across the world.
